NCBIDatasets Get Sequence Reports

Get per-sequence (chromosome/plasmid/scaffold) reports for a genome assembly via the NCBI Datasets v2 API. Returns each molecule's chromosome name, role, location type, RefSeq and GenBank accessions, length, and GC%. Use to map an assembly to its individual sequence accessions (e.g. resolve E. coli K-12 to NC_000913.3, or human chromosomes to their RefSeq NC_ accessions). No API key required.
